PDMDAAC (Polydimethyl diallyl ammonium chloride)

ʻO Polydimethyl diallyl ammonium chloride (PDMDAAC) kahi mea mālama wai multi-functional a kūpono hoʻi i ke kumukūʻai e hiki ke pani i nā mea kuʻuna he nui i nā kūlana like ʻole, e hāʻawi ana i nā pono koʻikoʻi e like me ka hoʻomaikaʻi ʻana i ka maikaʻi, ka hoʻemi ʻana i nā kumukūʻai, a me ka hoʻonui ʻana i ka pono. Hiki iā ia ke pani i nā mea hoʻohemo kala inorganic e like me ka polyferric sulfate a me ka polyaluminum chloride, a me ke kalapona i hoʻāla ʻia, me kahi dosage o 1/3 wale nō o nā mea kuʻuna, e hopena ana i nā helu decolorization kiʻekiʻe a me ka hana sludge hapalua. Hiki iā ia ke mālama pono i nā ʻano wai hoʻoheheʻe kala recalcitrant like ʻole, e hōʻemi nui ana i nā kumukūʻai hoʻolei sludge.

I ka manawa like, hiki iā ia ke pani i ka PAM cationic maʻamau, e hāʻawi ana i nā kumukūʻai haʻahaʻa, ka solubility maikaʻi, a me ka hana maʻalahi ma ka cationicity like. Hiki i ka hoʻohana hui pū ʻana ke hōʻemi i nā kumukūʻai ʻākena ma 30%, a hiki iā ia ke pani piha i nā hiʻohiʻona hoʻohemo wai sludge maʻamau. Eia kekahi, hiki iā ia ke pani i nā coagulants paʻakai alumini e like me ka alum a me ka polyaluminum sulfate, i hoʻopilikia ʻole ʻia e ka mahana o ka wai, e hana ana i nā flocs paʻa a wikiwiki hoʻi, e hoʻopau ana i nā pilikia koena alumini, a me ka hoʻopaʻa ʻana i ka maikaʻi o ka effluent.

Hiki ke hoʻohui pū ʻia me ka pauka hao e pani i ka lime hoʻomaʻemaʻe sludge, me ka ʻole o ka hoʻonui ʻana i ka nui o ka sludge, me ka waiho ʻole ʻana i nā haumia, a me ka hoʻomaʻalahi ʻana i ka mālama ʻana ma hope. ʻOiai ʻo ka sludge paʻakikī e koi ana i nā mea hoʻohuihui, ʻoi aku ka maikaʻi o ke kumukūʻai ma mua o nā mea hana kuʻuna. I ke aniau o kēia manawa o ka kaohi kumukūʻai koʻikoʻi a me ka ʻimi ʻana i ka effluent paʻa, ʻo PDMDAAC, me kona mau pono he nui o ka dosage haʻahaʻa, ka hana sludge haʻahaʻa, nā hopena paʻa, a me ka maʻalahi o ka hana, ua lilo ia i koho hoʻonui makemake ʻia no nā hale hana wai nui a me nā mea mālama wai e pani i nā mea hana kuʻuna, e hoʻokō maʻalahi ana i ka maikaʻi o ka mālama wai a me nā kumukūʻai i hoʻemi ʻia.
